Is this just my version or is it a server glitch with NPC Darius Crowley

Early in the Worgen area theres a mission flag where you hand in a quest and some characters speak to each other and at end of speech it triggers a new quest by speaking to one of the speaking NPCS.

On my first attempt the NPC was there and I tried the quest which was to lure worgens with flame whilst on horseback, if I remember its meant to either do more than 1 pass but I was kicked off the horse at the end of the 1st pass and unable to go back until I killed myself and spawned on the other side of the barricade.

The NPC wasn't there so I abandoned quest logged out, waited a day still nothing, tried going back and killing enemies or dying and respawning and nothing.

Eventually I deleted my character and tried the quests leading to it, I noticed another player doing the quest about a minute before I got there so they must of been fine but the NPC wasn't showing so I handed in previous quest which ends with the Greymanes having a speech to the quest giver NPC but as hes not there the event didn't finish.

Now I am stuck as the next quest won't trigger nor can I even fight enemies from the previous area as attacks do no damage.

I don't want to start yet again to have the same glitch.

So what is it? Me or the server?
